AB 2588 Air Toxics "Hot Spots" Program

This page last reviewed April 25, 2016


The Air Toxics "Hot Spots" Information and Assessment Act (AB 2588, 1987, Connelly) was enacted in 1987, and requires stationary sources to report the types and quantities of certain substances routinely released into the air. The goals of the Air Toxics "Hot Spots" Act are to collect emission data, to identify facilities having localized impacts, to ascertain health risks, to notify nearby residents of significant risks, and to reduce those significant risks to acceptable levels. A more general overview of the Act, including links to related legislation, is also available.

Facility Emissions and Risk Data Find information about toxic and criteria pollutants, including health risk information, for a specific facility using the Facility Search Tool.
“Hot Spots” Inventory Guidelines The Emission Inventory Criteria and Guidelines provide direction and criteria to facilities on how to compile and submit air toxics emission data required by the "Hot Spots" Program.
Fee Regulation Find information about State fees in the Air Toxics "Hot Spots" Program.
Prioritization The Air Toxics "Hot Spots" Information and Assessment Act requires local air districts to prioritize facilities to determine which facilities must perform a health risk assessment.
Risk Assessment The districts must consider the potency, toxicity, and quantity of emissions released from the facility to determine if the facility poses a significant risk.
Public Notification Once risk assessments are reviewed by the OEHHA and local air district, facility operators must notify all exposed persons of any significant cancer or non-cancer risks.
Risk Reduction Significant (high) risk facilities must reduce their toxic emissions and risk to acceptable levels.
